During the SGML19 Laser & Procedures in Zurich, information was also provided that a physician’s proviso for ablative laser procedures is under consultation with the Federal Office of Public Health [1]. It is planned that this regulation will be approved in the first quarter of 2019, as Dr. Bettina R\u00fcmmelein, specialist in dermatology FMH and president SGML, informed at the opening of the congress. Obtaining a specialty credential remains an optional qualification for dermatologists [3]. In Germany, a physician proviso is already enshrined in law.  <\/p>\n

Future-oriented application areas<\/h2>\n

Laser-assisted drug delivery (LADD) and photodynamic therapy (PDT) are particularly important among the new areas of application (box), explained Joachim Krischer, MD, specialist in dermatology and venereology FMH, Meyrin, in his presentation. LADD can increase the bioavailability of externally applied agents (e.g., cortisone, anesthetics, antitumor agents, botulinum toxin, antioxidants, etc.) [4]. As topically applied topical preparations are a central element of dermatological therapy, this is an extremely important optimization of dermatological therapy options. LADD allows controlled and standardized overcoming of the epidermal barrier function and has so far proven to be particularly useful in PDT [5].<\/p>\n

 <\/p>\n

As an example of a successful application of LADD (CO2 laser<\/sub> or erbium YAG laser), Dr. Krischer cites the treatment of cheilitis in the area of the upper lip with the result of the absence of lesions over several years. Regarding vitiligo, repigmentation was observed after about ten sessions. With regard to the risk of melanoma being induced in the process, there is currently still a need for research, said the speaker.<\/p>\n

Combination therapy with vascular laser has been shown to be effective, for example, in the treatment of angiomas that were refractory to vascular laser monotherapy. Traumatic hypertrophic or keloid scars are treated with a combination of fractional laser treatment and cortisone injections (administered beforehand). For scars after basal cell carcinoma, good results are obtained by starting in fractional mode and treating the redness with a vascular laser. Treatment with theCO2<\/sub> or Erbium YAG laser has also proven effective for cosmetically disturbing skin changes such as xanthelasma or sebaceous gland hyperplasia (benign skin tumors).<\/p>\n

Among the classic indications, the following are particularly common in everyday practice, according to the speaker: Warts, small cysts (e.g. in the eye area), wounds (traumatic, surgical), acne scars. In addition, fractional ablative laser continues to be routinely used to treat loss of elasticity, wrinkles, and other signs of photoaged skin) [3].<\/p>\n

Fractional lasers: favorable benefit-risk profile  <\/h2>\n

The advent of fractional lasers (on the market since 2004) revolutionized laser medicine [2]. Micro-pulses can be used to specifically destroy defined target structures. Unlike non-fractional lasers, the post-treatment period is less stressful and there are fewer complications (scars, infections, etc.). This has a positive effect on quality of life and patient satisfaction and outweighs the slightly better results of non-fractionated laser treatments.  Side effects that may occur in fractional mode (usually within 24h): Wound healing disorders, scarring, and hypo- or hyperpigmentation [6]. To minimize risks and undesirable side effects of ablative laser treatments, the following safety-related factors should be considered (Cave):<\/p>\n

    \n
  • Phototypes: <\/em>use only for type I-III (light skin types).<\/li>\n
  • Clinical diagnosis:<\/em> examine for atypical or tumoral lesions (e.g., melanoma in situ).<\/li>\n
  • Season: <\/em>not in summer; autumn\/winter is more suitable (UV exposure).     <\/li>\n
  • Sun exposure:<\/em> several weeks before and min. avoid one month after treatment (risk for hyperpigmentation)<\/li>\n
  • Herpes risk:<\/em> history and prophylaxis, if treatment face or genitals.<\/li>\n
  • Eye protection:<\/em> use laser goggles (patient and practitioner)<\/li>\n
  • Informed consent: <\/em>providing patients with sufficient information<\/li>\n
  • Laser smoke: <\/em>shield from exposure (carcinogenic particles)<\/li>\n
  • Local anesthesia:<\/em> only if necessary<\/li>\n
  • Unrealistic expectations: <\/em>refer patients if necessary.<\/li>\n
  • Photo documentation: <\/em>comparison before\/after<\/li>\n<\/ul>\n
